Oth fx fourth MC bone, left hand, subs for fx w routn heal

This code signifies a fracture of the fourth metacarpal bone in the left hand, which is not further specified as a Salter-Harris, comminuted, or other specific type. The patient is in a subsequent phase of care, and the fracture is progressing with expected routine healing.

This code is appropriate for follow-up encounters where a patient is receiving ongoing management for a previously diagnosed, non-specific fracture of the left fourth metacarpal. It indicates that the healing process is proceeding without complications or delays. This would be used after the initial treatment phase, such as cast changes, follow-up X-rays showing callus formation, or physical therapy sessions focused on regaining function while the bone continues to mend.

• Ensure documentation specifies "left hand" and "fourth metacarpal" for accurate laterality and bone identification.
• Verify that the encounter is for a subsequent phase of care and that healing is documented as routine.
• Do not use for initial treatment or for fractures with delayed healing, nonunion, or malunion.
